Abstract
This paper presents a simple but still powerful approach for the analysis of the average power consumption of a sensor node using the IPv6 over Low power and Lossy Networks (LLN) stack, which is one of the most widely adopted and promising communication stacks. Power consumption is broken down according to the node states (i.e. CPU, IRQ, LPM, Tx, Rx) and according to the network protocols (e.g. CoAP, RPL, 6LoWPAN, Contiki MAC), identifying the relative weight of each protocol in the total energy consumption for several configurations. Results show that the Low Power Listening (LPL) mechanism of the radio duty cycling layer and RPL control messages have the highest impact on the total energy consumption, while the application's report rate has a very low impact for periods over 60 seconds.
本文提出了一种简单但仍然强大的方法来分析传感器节点的平均功耗，使用IPv6 over Low power and Lossy Networks (LLN)堆栈，这是最广泛采用和最有前途的通信堆栈之一。功耗根据节点状态(如CPU、IRQ、LPM、Tx、Rx)和网络协议(如CoAP、RPL、6LoWPAN、Contiki MAC)进行分解，确定各种配置下各协议在总能耗中的相对权重。结果表明，无线电占空比层的低功率收听(LPL)机制和RPL控制消息对总能耗的影响最大，而应用程序的报告率在超过60秒的时间内的影响非常小。
